“Olivet Presbyterian Church was the outgrowth of a Sunday School started on Aug. 5, 1849 in a frame building known as Hedgeville School with E. T. Taylor as Superintendent. It was located at the corner of Newport Road and Dock Street, now the southerly side of Maryland Ave., about 320 feet west of Front St., Dock St., in the meantime, having been vacated. The Sunday School was sponsored by Hanover Church who purchased the building. Prayer meetings and preaching were maintained for a number of years.
The congregation was organized as a church on Jan. 31, 1863. The cornerstone of a new building, known as Olivet Chapel, at Adams and Chestnut Sts., was laid on Oct. 8, 1863.

The present site at the s. w. cor. of 4th and Broom Sts., was purchased on Dec. 31, 1887 from the Trustees of the Poor. It was a portion of the old New Castle County Almshouse property. The erection of a Sunday School building was started in October, 1887. The present church was built in 1891.

The service was conducted by the Rev. Dr. William B. Pugh, Stated Clerk of the Presbyterian General Assembly.
